实现手机语音通话的Vue方案

在Vue中实现手机语音通话功能，通常需要结合WebRTC技术和第三方通信服务。以下是几种常见实现方式：

使用WebRTC实现点对点通话

WebRTC是浏览器原生支持的实时通信技术，适合构建点对点通话应用：

安装WebRTC相关依赖：

npm install peerjs simple-peer

创建语音通话组件：

<template>
  <div>
    <button @click="startCall">开始通话</button>
    <button @click="endCall">结束通话</button>
    <audio ref="remoteAudio" autoplay></audio>
  </div>
</template>

<script>
import Peer from 'peerjs'
import SimplePeer from 'simple-peer'

export default {
  data() {
    return {
      peer: null,
      localStream: null,
      remoteStream: null
    }
  },
  methods: {
    async startCall() {
      this.localStream = await navigator.mediaDevices.getUserMedia({ audio: true })

      this.peer = new SimplePeer({
        initiator: true,
        stream: this.localStream
      })

      this.peer.on('signal', data => {
        // 发送信令数据给对方
      })

      this.peer.on('stream', stream => {
        this.$refs.remoteAudio.srcObject = stream
      })
    },
    endCall() {
      if (this.localStream) {
        this.localStream.getTracks().forEach(track => track.stop())
      }
      if (this.peer) this.peer.destroy()
    }
  }
}
</script>

使用第三方通信服务

对于更稳定的生产环境，建议使用专业通信平台如Twilio或Agora：

安装Agora SDK：

npm install agora-rtc-sdk

实现基础通话功能：

<script>
import AgoraRTC from 'agora-rtc-sdk'

export default {
  data() {
    return {
      client: null,
      localStream: null
    }
  },
  methods: {
    async initAgora() {
      this.client = AgoraRTC.createClient({ mode: 'rtc', codec: 'vp8' })

      await this.client.init('YOUR_APP_ID')
      await this.client.join('YOUR_TOKEN', 'channelName', null, uid)

      this.localStream = AgoraRTC.createStream({ audio: true, video: false })
      await this.localStream.init()
      this.client.publish(this.localStream)

      this.client.on('stream-added', evt => {
        this.client.subscribe(evt.stream)
      })

      this.client.on('stream-subscribed', evt => {
        const remoteStream = evt.stream
        this.$refs.remoteAudio.srcObject = remoteStream
      })
    }
  }
}
</script>

实现信令服务器

对于WebRTC方案，需要实现信令交换服务：

创建简单的Socket.io信令服务器：

// server.js
const express = require('express')
const socketIO = require('socket.io')

const app = express()
const server = app.listen(3000)
const io = socketIO(server)

io.on('connection', socket => {
  socket.on('offer', data => {
    socket.broadcast.emit('offer', data)
  })

  socket.on('answer', data => {
    socket.broadcast.emit('answer', data)
  })

  socket.on('ice-candidate', data => {
    socket.broadcast.emit('ice-candidate', data)
  })
})

移动端适配注意事项

针对手机浏览器的特殊处理：

添加响应式布局适应不同屏幕尺寸
处理iOS的自动播放限制
添加权限请求提示
优化音频编解码设置

<template>
  <div class="call-container">
    <button 
      @click="requestMicrophone" 
      v-if="!permissionGranted"
    >
      允许麦克风访问
    </button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      permissionGranted: false
    }
  },
  methods: {
    async requestMicrophone() {
      try {
        await navigator.mediaDevices.getUserMedia({ audio: true })
        this.permissionGranted = true
      } catch (error) {
        console.error('麦克风访问被拒绝:', error)
      }
    }
  }
}
</script>
